WebThe flash point of a coating is the lowest temperature at which vapors above that liquid will burn when exposed to a source of ignition (i.e., a flame). Flash point is a direct function of the solvent system. A coating's flash point is typically that of the most volatile solvent in the solvent system. Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH3CO)2O.
